System & Software Testing for Safety-Critical Applications Training by Tonex
Built for teams who verify complex, high-assurance systems, this program sharpens strategy, technique, and evidence-based reporting for safety certification. Participants learn to connect hazards, requirements, and tests into a defensible safety case while scaling coverage across real-time and embedded contexts.
Cybersecurity intersects safety at every layer—threats can trigger hazardous behavior, and mitigations must be validated like any other safety requirement. You’ll practice designing tests that verify both safety controls and security hardening without inflating cycle time. By the end, you’ll know how to structure traceability, automate checks, and present objective results that satisfy regulators and program leadership.
Learning Objectives
- Build a risk-driven safety test strategy aligned to standards and assurance cases
- Translate safety requirements and hazards into verifiable, prioritized test conditions
- Design tests for real-time and embedded behaviors, timing, and concurrency
- Apply MC/DC and structural coverage evidence to complement scenario testing
- Engineer stress, fault-injection, and robustness campaigns with actionable metrics
- Integrate continuous verification, tooling, and analytics into delivery pipelines
- Write one objective on cybersecurity: validate that cybersecurity controls do not degrade safety and that safety mechanisms withstand cybersecurity threats
